Annual boiler servicing
Why service your gas boiler every year?
An annual service is planned maintenance: it supports safe operation, gives an engineer a chance to spot deterioration and helps you keep the service history many warranties require. It cannot promise that a boiler will never break down, but it is a far better plan than waiting for a cold morning to find out something is wrong.
Maintenance, not guesswork
The work should follow the service instructions for your make and model. A modern condensing boiler does not automatically need the same routine as an older boiler.
Warranty records
Many boiler warranties require annual servicing by a suitably qualified engineer. Keep the completed service record and check the exact terms for your boiler.
What the £105 service includes
A proper boiler service follows the boiler, not a generic checklist
Not every boiler service is identical. We use the manufacturer's instructions for the appliance and carry out the checks and maintenance that apply to that boiler.
Safety, flue and combustion checks
We visually inspect the boiler and accessible flue, check safe operation and complete combustion checks where the manufacturer's routine requires them.
Cleaning and boiler maintenance
We inspect and clean the relevant components for the model. Older non-condensing boilers and modern condensing boilers can have different service requirements.
Pressure, condensate and expansion vessel
We check system pressure, clean the condensate trap if the boiler has one, and check the expansion vessel. If it needs recharging as part of the service, we pump it back up.
Service record and practical advice
We complete the service record and explain anything we find, including age-related parts or maintenance that may be worth planning rather than leaving as a surprise.
Before the appointment
Tell us about faults, leaks or pressure loss when you book
A service is not the same as fault diagnosis. If the boiler has stopped working, shows a fault code, makes an unusual noise, leaks or keeps losing pressure, tell us before the visit. Diagnosis or repair may need to come first, and advance information can help us plan the right appointment or bring a likely part.
If the boiler is working normally
Use the £105 online booking diary. Make sure the boiler, controls and gas meter are accessible, and keep the manual or warranty record nearby if you have it.
If the boiler has a fault
Tell us what is happening in the enquiry notes or arrange a boiler repair in Lincoln. We will help you choose the right type of visit.

Frequently asked questions
Gas boiler service FAQs
What is included in the £105 gas boiler service?
We follow the service routine for your boiler and complete the relevant visual, safety, flue and combustion checks, cleaning and maintenance. We also check system pressure, the condensate trap and expansion vessel where applicable, then complete the service record. The £105 price includes travel within 15 miles of Lincoln; the diary shows any distance surcharge before you book.
How often should I have my boiler serviced?
Annual servicing is the normal schedule for a domestic gas boiler. It supports safe operation, planned maintenance and the servicing requirements found in many manufacturer warranties.
How long does a boiler service take?
A straightforward gas boiler service normally takes 30 to 45 minutes overall. Around 30 minutes is spent on the boiler, with the remaining time used for wider checks, recording results and paperwork. Report any known fault when booking because diagnosis or repair needs a different appointment.
Do I need annual servicing for my boiler warranty?
Check the terms for your boiler. Many manufacturers require an annual service by a suitably qualified engineer and may ask for the service record if you make a warranty claim.
What should I do before my boiler service?
Please turn the boiler off about one hour before the appointment so it is safe to work on; a modern boiler may need less time because it does not get as hot. Make sure the boiler, heating controls and gas meter are accessible, and tell us before the visit about fault codes, leaks, unusual noises or pressure loss.
Can you fix faults during a service?
A service is planned maintenance rather than a fault-diagnosis appointment. A small issue may sometimes be dealt with during the visit, but a boiler with a fault, leak or breakdown may need diagnosis or repair first. Tell us when booking so we can plan the right appointment.
Can you service LPG, oil or heat-pump systems?
Yes, but not through this £105 mains gas diary. Choose LPG, oil or heat pump from the prominent service options near the top of this page.
